IMPROVEMENT IN WATER-WHEELS.

"die Srlgnule niettemin in time t-tinta tant mit uniting putti its smite TO ALL WHOM IT MAY CONCERN: l

Be it known that I, ISAAC S. ROLAND, of Reading, in the county of Berks,and State of Pennsylvania, `have invented a new and useful Improvement4 in Water-Wheels; and I do hereby declare that 'the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part of this specificationi Figure 1 being a top view of my improved water-wheel. Figure 2l, a. section in the line :c a: of iig. 1. 4 A Figure 3, a top view of saidwheel, with a'portio'n thereof removed, for the purpose offmbreclcarly showing the shape and arrangement of the buckets thereof; and v i Y Figure 4, a side view'iof an auxiliaryportion of the wheel detached therefrom.,

Similar letters indicate like parts in all the drawings. l The vertical shaft A of my improved water-wheel may be sustained by means of a suitable step and journalbox, and in any well-known or usual manner.

The portion of thebucket-,head or disk B, of my improved water-wheel, which receives the lower edges of the buckets c e, is curved idownwards;` as shown in iig. 2. The upper edges of said series of buckets c c are connected with each other by 'meansfof the downwardly-.curving rim' d, tig. 2. This rim d is not shown in fig.

3, the said omission being for the purpose of more clearly showing the shape and arrangement ofits buckets Y c c, and also the arrangement of said buckets with relation tothe buckets ff of the water-supplying chutechamber fj k Z, which Ais located within the series of buckets c c of the water-wheel, as shown in-iig. 2. -This chute-chamber is composed of the upper rim jk, the series of chute-buckets ff, and the lower rim ll The upper ends of the buckets ff are connected to the inner' portion,'j, ,of the upper rimj la, and the lower ends oi' said buckets are connected to the lower rim l, as shown in tig. 3. An annular and upwardly-curving rim, g,

which rests upon and is secured to the perforated base-supporter m, receives and supports the chutechamber Zin its proper location .within the series of water-wheel buckets c c, and in such a manner that the saidchute-chamber is allowed to-turn freely upon its supporter, and adjustitself` to the best positionwithin the water-wheel. YThe lip lc, which radiates from the head of the chute-chamber, and overlaps the inner periphery' of the annular supporter g, furnishes the proper means of suspending said chamber in its position within the waterfwheel. l p l l When my improved water-wheel is located, as-it frequently is, in tl1e bottom of a flume or water-box, the

base-supporter m, in iig. 2, represents the position of thebottom of said Hume or water-box, and in that case,

the upwardly-aring annular rim g rests on the edge of the opening in the bottom of said-ume or ibex?, whilst the water-wheel shaft rests upon a properly-snppertedI step, n, beneath the umeor water-box, -as shown in said drawing. v Y Y ,The chute-chamberfj c l not 4being confined in its position up'on and within its supporter g, the action and reaction of the water, as it escapes therefrom and strikes against the series of water-wheel buckets, ordinarily keeps the said chute-chamber` `ina stationary position; but .when lany solid obstacleV may find its way into the chute-chamber, and be caughtbetween the buckets thereof and the buckets of the water-wheel, the chute-chamber will thereby be made to rotate withV the water-wheel, withoutproducing 'any injury to either, and the wheel will be speedily brought to a stand-still, when the attendant can readily remove said obstruction, and one, perhaps, which, had it been discharged from-a stationary chutepvould probably have greatly injured or destroyed the wheel. Y

A tubular gate, 71, fits accurately within the chutecbamber fj Itr l, and to opposite sides of said tubular gate, vertical rods z' i are secured, which pass upwards, and are `connected to any suitable contrivance for raisin'g or depressing said gate, for the purpose of regulating the amount of water that it may be desired to admit .to'thc buckets oi' the waterfwheel.

I do not intend to-limit myself to any precise shape or number' of the buckets ff in the chute-chamber f j Je l, nor do I intend to limit myself to any p'reeise shape or number of the buckets -in the water-wheel. v

Havingl thus fully described my improved mater-wheel,l what I claim therein as my invention, and desire to secure by Letters Patent; isl The movable and self-relieving ohuteohamber f 7' k l, located within the series of water-wheel buckets c c, and'operating therewith, substantially as herein se!l forth.

^ I also claim the arrangement of the movable chute-chamber fj k Z, and its annular supporter g, with'th disk and buckets of the water-wheel, substantially as herein Set forth.

I also claim the combination of the tubular gate h with said movable ohute-hamber, arranged and operating substantially as herein set forth.

The aforegoing speciiicationof my new and useful improvements in water-wheels signedand witnessed, this 10th day ofi-June, 1868.
